Abstract

The exchange of information takes place at hyperfrequency, the ground station being connected to a waveguide (25), and the station on the railway vehicle being connected to an antenna (26). Each station comprises a hyperfrequency generator (19) supplying a carrier, emitters (3 to 7) supplying subcarriers, receivers (28 to 32) and a pilot generator (1). The carrier and the subcarriers have frequencies which are multiples of the pilot frequency, the frequency deviation between two successive subcarriers being equal to the pilot frequency. An emission mixing unit (MTX) receives the carrier and the subcarriers and is connected to a circulator (24) which is itself connected to the waveguide (25) in the ground station and to the antenna on the vehicle. <??>A reception mixing unit (MRX) is connected by a filter (23) to the circulator (24) and receives the hyperfrequency generator carrier; it is connected to the receivers (28 to 32) to which it supplies the subcarriers emitted by the other station. <IMAGE>
